On this day 205 years ago at approximately 2:15 a.m., a magnitude ~7.5 earthquake struck northeast Arkansas and the Missouri Bootheel region. It was the first of three main shocks and hundreds of aftershocks in the New Madrid Seismic Zone that winter. Because of the sparse population in the epicentral area at the time, the earthquake caused only slight damage to man-made structures. This would not be the case today if a similar quake was to occur, as about 12 million people now live in the St. Louis–Memphis region. Learn more about this event at http://on.doi.gov/2h4LqEY.
